[gmx-users] how to use the trjconv -sep and -skip to get the individual file

[Francesco]

if you only want the pdb file at a specific moment you can use -dump
trjconv -f traj.xtc -s file.tpr -o pdb_at_time.pdb -dump 10

the "pdb_at_time.pdb" file will be the structure at 10 ps.

You can then write a script to go through all your simulation.

cheers
